Osram/Sylvania fluorescent tubes
Richard Sexton
I'd like to hear if there are any tubs people can't find or
can't find easily, especially CF biax and euro-only ones.
What do you guys in Europe use?

Some blueish expesnive bulb. I swear people pick
tubes bases on how expensive and hard to get they
are. I use warm white CF tbes because they're cheap
and a mix of gro lux and C50 tubes cause I like the
pretty colors.

Fresh water:
Many Dutch-like plant tanks of the early 70s were running
without any colourful tubes. In the contrary those days one
had tubes _less_ effective than those referred to you.
Salt water:
Let me differentiate cold water, mediterranean and
tropical.
Cold water tanks need _less_ light, they were running with
less cool white. Never had any problems.
Mediterranean tanks were running (think about the angle of
refraction of sun light..) with those cool white tubes
referred to you, too. Never had any problems.
Tropical:
Tropical tanks with species that live close to the surface:
Close to the surface marine light is similar to sun light.
Fish or caulerpa tanks and some anemone tanks were running
with cool white. I had Nanos running with simple energy
lamps, too.
Tropical tanks with sensitive animals that live in symbiosis
to photo active algae often need much more light and a light
that on the one hand help to avoid the growing of green
algae what might cover or stifle these animals (or possibly
green algae eaters..?) and on the other hand has more blue
benefit to the photo active algae, but not to the
disturbing green. I think here were marine tubes or HQX
(I'm not familiar to both, *I and *L) the best choice.
Just my personal insights. Of course optimised tubes will
have benefit, but I believe in the power of the human
"factor", too. ;-)

I picked up a book from the remainders table at a local bookseller,
you know, big red sticker $3.98 reduced from twenty bucks because no
one will buy the darn thing. It was an encyclopedia of tropical
fishes, as if we need another one. It was published in the
Netherlands. Under the lighting section, the author referred
repeatedly about the benefits of his "neon" lights. I begin to wonder
if neon was his term for flourscents, but a couple of paragraphs later
he discussed flourescent tubes. Does anyone know what he was talking
about regarding neons?

Neon lights are those were the tube is filled with Neon gas - or so I
believe - much the same sort of thing that you used to see on shop
fronts or at Picadilly Circus (and I guess Times Square)

In my childhood we said "Neonlampen" (neon lamps) too, but
did mean fluorescent tubes.
In the aquaria of the 60s and 70s fluorescent tubes
displaced more an more these lamps:

OK. Yes, I know them as the bent tube lights in beer signs . . . but
what is their application with aquariums?

AHA! Now we're getting somewhere. Thanks.
